510290 ÷ 48 
The aim is to understand the frequency of 48 in 510290.

Step 1:
If we divide 5 by 48, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 48

Let's proceed to step 2:
51 divided by 48 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 48 from 51 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 48

Going ahead to step 3:
30 divided by 48 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 30 to get 30.
Grab the next digit (2) from the dividend, add it to 30, then carry on: 302 / 48

Step 4:
48 goes into 302 6 times with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 106.0
The remainder is 14 after subtracting 288 from 302.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 48

On to step 5:
149 divided by 48 is 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 1063.0
Subtract 144 from 149 to get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 48

Let's proceed to step 6:
48 can be fit into 50 1 times, resulting in a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 10631.0
The remainder is 2 after subtracting 48 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
When dividing 20 by 48, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 10631.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
The number 48 fits into 200 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 10631.04
If we take 192 away from 200, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
When dividing 80 by 48, we get 1 with a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 10631.041
Subtract 48 from 80 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
48 can be fit into 320 6 times, resulting in a remainder of 32.
The next digit of our result is 6. 
Result so far: 10631.0416
Subtract 288 from 320 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 11:
320 divided by 48 is 6 with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 10631.04166
If we take 288 away from 320, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 10631.04166 with a remainder of 3.2e-05.
